	4.	COMMON SHARES SUBJECT TO THE PLAN AND INSIDER PARTICIPATION LIMITS 

  

	4.1	Common Shares Subject to Options 

 Subject to adjustment as described in
Section 11, the aggregate number of common shares issuable pursuant to Options under the Plan will not exceed the fixed number of shares approved by shareholders of the Corporation from time to time, which as of the Effective Date is 19,750,000
common shares (subject to shareholder approval). At all times, the Corporation will reserve and keep available a sufficient number of common shares to satisfy the requirements of all outstanding Options granted under the Plan and awards under any
other Security-Based Compensation Arrangements of the Corporation. 
  

	4.2	Common Shares Deducted from the Plan Reserve / Available for Future Grants 

 Subject to
the rules of any stock exchange upon which the common shares are then listed: 
  

	 	(a)	for each Option that terminates, expires or is cancelled or forfeited, each common share subject to such Option will, to the extent of such termination, expiration, cancellation or forfeiture, be returned to the plan
reserve and again be available for issuance; 

  

	 	(b)	for each Option that is exercised and settled, each common share subject to such Option will be deducted from the plan reserve. 

  

	4.3	Insider Participation Limits 

 Notwithstanding anything to the contrary contained in the
Plan, no Options will be granted to Insiders if such Options, together with any other previously established Security-Based Compensation Arrangements, could result in: 

  
 3 









	 	(a)	the number of common shares issuable to Insiders at any time pursuant to Security-Based Compensation Arrangements of the Corporation exceeding 10% of the issued and outstanding common shares; or 


 

	 	(b)	the issuance to Insiders pursuant to Security-Based Compensation Arrangements of the Corporation, within any one-year period, of a number of common shares exceeding 10% of the
issued and outstanding common shares. 

 Any entitlement to acquire common shares granted pursuant to the Plan or other
Security-Based Compensation Arrangement prior to the Participant becoming an Insider will be excluded for the purposes of the limits set out in this Section 4.3. 
  

	4.4	Fractional Common Shares 

 No fractional common shares will be issued upon the exercise
or settlement of Options in common shares, and the Corporation may determine the manner in which fractional share value will be treated. 
  

	5.	OPTIONS 

  

	5.1	Grant 

 Options may be granted to Eligible Participants at such time or times as will be
determined by the HR&CC by resolution. The Grant Date of an Option for purposes of the Plan will be the date on which the Option is awarded by the HR&CC, or such later date determined by the HR&CC, subject to applicable law. 

 

	5.2	Terms and Conditions of Options 

 Options will be evidenced by an Option Award
Agreement, which will specify such terms and conditions as the HR&CC will determine (subject to the specific provisions of the Plan), including: 
  

	 	(a)	the number of Options to be granted to the Eligible Participant; 

  

	 	(b)	the Exercise Price, which will in no event be less than the Fair Market Value on the Grant Date; 

  

	 	(c)	the scheduled expiry date of the Option, which will not exceed the 10th anniversary of the Grant Date (provided that if no specific determination as to the scheduled
expiry date is made by the HR&CC, the scheduled expiry date will be 10th anniversary of the Grant Date); and 


 

	 	(d)	such other terms and conditions as the HR&CC determines, including customary representations, warranties and covenants with respect to securities law matters. 


For greater certainty, each Option Award Agreement may contain terms and conditions in addition to those set forth in the Plan that are not
inconsistent with the Plan. 
  

	5.3	Option Accounts 

 A separate notional account will be maintained for each Participant
with respect to Options (an Option Account) granted to such Participant in accordance with Section 15.3. Options awarded to the Participant from time to time pursuant to Section 5.1 will be credited to the Participant’s Option
Account and will vest in accordance with Section 5.4. On the vesting of Options pursuant to Section 5.4 and the corresponding exercise and settlement pursuant to Section 5.5, or on termination, expiration or forfeiture of the Options
pursuant to the terms of the Award, the Options credited to the Participant’s Option Account will be cancelled. 

  
 4 









	5.4	Vesting 

 Subject to any other provision of the Plan, unless otherwise determined by the
HR&CC, or unless otherwise specified in the Participant’s Executive Employment Agreement or Option Award Agreement, each Option will vest as to one-quarter of the number of common shares granted by
such Option on each of the first through fourth anniversaries of the Grant Date, subject to continuous employment of the Participant with the Corporation or Affiliate (as applicable) until the vesting date. 

 

	5.5	Exercise and Settlement of Options 

 Only vested Options may be exercised. Options may
be exercised by the Participant by delivering to the Corporation a notice of exercise specifying the number of common shares covered by the Options that are being exercised. Payment of the Exercise Price may be made by one or more of the following
methods (or any combination thereof): 
  

	 	(a)	in cash, by certified cheque made payable to the Corporation, by wire transfer of immediately available funds or other instrument acceptable to the Corporation; 


 

	 	(b)	if permitted by the Corporation, by a broker-assisted “cashless exercise” arrangement pursuant to which the Participant delivers to the Corporation a copy of irrevocable instructions given by the Participant
to a stockbroker to sell the common shares otherwise deliverable upon the exercise of the Option and to deliver promptly to the Corporation an amount equal to the Exercise Price and any required withholding taxes against delivery of the common
shares subject to such Option to settle the applicable trade; or 

  

	 	(c)	if permitted by the Corporation, by a “net exercise” arrangement pursuant to which the Corporation withholds a number of common shares subject to such Option otherwise deliverable upon the exercise of the
Option (or allows the Participant to surrender Options for such number of common shares otherwise deliverable upon the exercise of the Option) in an amount equal to the Exercise Price and any required withholding taxes. 


No common shares will be issued until all requirements contained in the Plan, the Option Award Agreement and under applicable law to settle
the Options on exercise thereof have been satisfied and completed. 
  

	6.	TERMINATION OF EMPLOYMENT 

  

	6.1	Treatment of Options Due to Termination of Employment 

 Unless otherwise determined by
the HR&CC (or by the Chair of the HR&CC in circumstances involving individual Participants), or unless otherwise provided in the Participant’s Executive Employment Agreement or Award Agreement, and subject to Section 8, if a
Participant’s employment terminates in any of the following circumstances, Options will be treated in the following manner: 

  
 5 









			
	 Reason for

Termination of

Employment
	  	 Treatment of Options

	Death (including while Retired) or Disability	  	Options credited to the Participant’s Option Account as of the date of death or Disability that are unvested shall automatically vest as of such date, and such vested Options (including by reason of accelerated vesting) must
be exercised by the earlier of the scheduled expiry date of the Option and the end of the 12th calendar month following the calendar month of the date of death or Disability, and thereafter such
Options automatically terminate and are forfeited.
		
	Retirement	  	 Options credited to the Participant’s Option Account prior to the beginning of the calendar year in which the date of Retirement
occurs that are unvested shall continue to vest as if the Participant had continued active employment until, and such Options, to the extent vested (including those that continue to vest post-Retirement), must be exercised by, the earlier of the
scheduled expiry date of the Option and the end of the calendar month in which the 5th anniversary of the date of Retirement occurs, and thereafter such Options automatically terminate and are
forfeited.
  
 Options credited to the Participant’s Option Account in the calendar
year in which the date of Retirement occurs that are unvested will be pro-rated1 to reflect the actual period between the start of the calendar year in
which the date of Retirement occurs and the calendar month of the date of Retirement. Such pro-rated Options shall continue to vest as if the Participant had continued active employment until, and such pro-rated Options, to the extent vested (including those that continue to vest post-Retirement), must be exercised by, the earlier of the scheduled expiry date of the Option and the end of the calendar month in
which the 5th anniversary of the date of Retirement occurs, and thereafter such Options automatically terminate and are forfeited.

		
	Resignation without Good Reason	  	 Options credited to the Participant’s Option Account that are unvested as of the Termination Date shall automatically terminate and
are forfeited.
 Options credited to the Participant’s Option Account that are vested as of the Termination Date must be exercised by the earlier of the
scheduled expiry date of the Option and the end of the 3rd calendar month following the calendar month of the Termination Date, and thereafter such Options automatically terminate and are
forfeited.

		
	 Termination without
 Cause or Resignation

for Good Reason –
 No Change in Control Involved
	  	Options credited to the Participant’s Option Account as of the Termination Date that are unvested continue to vest as if the Participant had continued active employment until the earlier of the scheduled expiry date of the
Option and the Severance Date, and such Options, to the extent vested (including those that continue to vest post-Termination Date), must be exercised by the end of the 3rd calendar month
following the calendar month of the Severance Date, and thereafter such Options automatically terminate and are forfeited.
		
	Change in Control	  	Options credited to the Participant’s Option Account as of (x) the CIC Date (in the circumstances set forth in Section 7.1(a)(i)) or (y) the Termination Date (in the circumstances set forth in Section
7.1(a)(ii)), vested or unvested, shall be treated solely in accordance with Section 7.
		
	Termination with Cause	  	Options credited to the Participant’s Option Account as of the Termination Date, vested or unvested, automatically terminate and are forfeited.

  

	6.2	No Further Awards or Damages 

 For greater certainty, on the cessation of the
Participant’s employment for any reason, whether on, before or after the Termination Date or any other relevant date referred to in Section 6.1, the Participant will have no further entitlement to grants of Awards, and will not be
entitled to any compensatory payments, damages or other amounts arising from or related to Awards that are terminated and/or forfeited in accordance with this Section 6. 

 

	1 	Instruction: Pro-rated = (i) the number of unvested Options credited to the Participant’s Option Account in the calendar year in which the date of Retirement occurs,
multiplied by (ii) a fraction, the numerator of which is the number of full calendar months from the start of the calendar year in which the date of Retirement occurs through to the calendar month of the date of Retirement (inclusive) and the
denominator of which is 12. All remaining Options automatically terminate and are forfeited.

	7.	CHANGE IN CONTROL 

  

	7.1	Change in Control – Double Trigger Vesting and Settlement 

 Unless otherwise
determined by the HR&CC, or unless otherwise provided in the Participant’s Executive Employment Agreement or Award Agreement, Awards will be treated in the following manner: 

 

	 	(a)	If a Change in Control occurs and at least one of the 2 additional circumstances described below occurs: 

  

	 	(i)	upon the effective date of the Change in Control (the CIC Date) the surviving corporation (or any affiliate thereof) or the potential successor (or any affiliate thereof) fails to continue or assume the
obligations with respect to each Award or fails to provide for the conversion or replacement of each Award with an equivalent award that satisfies the criteria set forth in Section 7.1(b)(i) or 7.1(b)(ii); or 


 

	 	(ii)	if the Awards are continued, assumed, converted or replaced as contemplated in 7.1(a)(i), or if Awards are granted to the Participant during the 2-year period following the CIC
Date and, in either case, during the 2-year period following the CIC Date, the Participant is terminated without Cause or the Participant resigns for Good Reason, 


each unvested Award credited to the Participant’s Option Account as of (x) the CIC Date (in the circumstances set forth in
Section 7.1(a)(i)); or (y) the Termination Date (in the circumstances set forth in Section 7.1(a)(ii)) shall automatically vest as of such date. 
  

	 	(b)	For purposes of Section 7.1(a)(i): 

  

	 	(i)	the obligations with respect to each Award will be considered to have been continued or assumed by the surviving corporation (or any affiliate thereof) or the potential successor (or any affiliate thereof) if each of
the following conditions are met, which determination will be made by the HR&CC, which determination may be made in advance of the CIC Date and will be final and binding, subject to applicable law: 


 

	 	(A)	the common shares remain publicly held and widely traded on an established stock exchange; 

  

	 	(B)	the terms of the Plan and each Award are not materially and adversely affected without the consent of the Participant; and 

  

	 	(ii)	the obligations with respect to each Award will be considered to have been converted or replaced with an equivalent award by the surviving corporation (or any affiliate thereof) or the potential successor (or any
affiliate thereof), if each of the following conditions are met, which determination will be made by the HR&CC, which determination may be made in advance of the CIC Date and will be final and binding, subject to applicable law:


  

	 	(A)	each Award that is subject to Section 7 of the Income Tax Act (Canada) is converted or replaced with a replacement award in a manner that qualifies under Subsection 7(1.4) of the Income Tax Act
(Canada) in the case of a Participant that is a Canadian Taxpayer or that complies with Code Section 409A in the case of a Participant that is a US Taxpayer on all or any portion of the benefit arising in connection with the grant, exercise,
settlement and/or other disposition of such award; 


  
 7 









	 	(B)	the converted or replaced award preserves the existing value of each underlying Award being replaced, contains provisions for scheduled vesting and treatment on termination of employment (including with respect to the
definitions of Cause and Good Reason) that are no less favourable to the Participant than the underlying Award being replaced, and all other terms of the converted award or replacement award (including with respect to the Exercise Price and Exercise
Periods (as applicable), but other than the number and type of security represented by the continued Award or replacement award) are substantially similar to the underlying Award being converted or replaced; and 


 

	 	(C)	the security represented by the converted or replaced Award is of a class that is publicly held and widely traded on an established stock exchange. 


 

	 	(c)	If the circumstances set forth in Section 7.1(a)(i) occur, Awards will be treated in the following manner: 

  

	 	(i)	subject to and conditional upon completion of the Change in Control, the Participant will be entitled to receive, as soon as practicable after the CIC Date, for each vested Award (including by reason of accelerated
vesting) credited to the Participant’s Option Account as of the CIC Date, either (x) common shares or (y) cash, at the discretion of the Participant, in each case equal to the excess of the Fair Market Value per common share as of the
Business Day immediately preceding the CIC Date over the Exercise Price of the Option, and thereafter all Options will automatically terminate and be forfeited with no further act or formality;
and 

  

	 	(ii)	if the Change in Control is not completed, the Corporation may revoke any action previously taken under this Section 7.1(c) by written notice to the Participant and Awards will thereafter continue to be allocated
to the Participant in accordance with their terms. 

  

	 	(d)	If the circumstances set forth in Section 7.1(a)(ii) occur, each vested Option (including by reason of accelerated vesting) credited to the Participant’s Option Account as of the Termination Date must be
exercised by the scheduled expiry date of the Option, and thereafter such Options automatically terminate and are forfeited. 

  

	7.2	Change in Control 

 Notwithstanding Section 7.1, in the event of a Change in
Control, the HR&CC will have the right, but not the obligation, and without the consent of any Participant, to permit each Participant, within a specified period of time prior to the completion of the Change in Control as determined by the
Corporation, to exercise or settle all of the Participant’s vested Awards (to the extent then vested and exercisable, including by reason of acceleration pursuant to Section 7.1 or by the HR&CC pursuant to Section 7.3), subject to
and conditional upon the completion of the Change in Control. 
  

	7.3	Discretion to Accelerate Awards 

 Notwithstanding Section 7.1, in the event of a
Change in Control, the HR&CC may accelerate the dates upon which any or all outstanding Awards will vest and be exercisable or settled, without regard to whether such Awards have otherwise vested in accordance with their terms. 

  
 8 









	7.4	Further Assurances on Change in Control 

  

	 	(a)	The Corporation shall use its best efforts to provide for the reservation and issuance by the surviving corporation (or affiliate thereof) or the potential successor of an appropriate number of common shares, with
appropriate adjustments, so as to give effect to any continuance, assumption, conversion or replacement of the Awards under Section 7.1(a)(i) or otherwise to give effect to this Section 7. 


 

	 	(b)	The Participant shall execute such documents and instruments and take such other actions, including exercise of vested Options, as may be required consistent with the foregoing. 


 

	7.5	Awards Need Not be Treated Identically 

 In taking any of the actions contemplated by
this Section 7, the HR&CC will not be obligated to treat all Awards held by a Participant, or all Awards in general, identically. 
  

	7.6	No Further Awards or Damages 

 For greater certainty, the Participant shall have no
further entitlement to grants of Awards from and after the CIC Date or Termination Date (as applicable) arising from or related to a particular Change in Control, and shall not be entitled to any compensatory payments, damages or other amounts on
account of Awards that are terminated and/or forfeited in accordance with this Section 7. 
  

	8.	COMMITTEE DISCRETION 

 Notwithstanding any other provision of the Plan and subject to
applicable law, the HR&CC may grant Awards at such times and on such terms and conditions as it may determine including on different vesting conditions than those specifically provided in the Plan, to accelerate the dates upon which any or all
outstanding Awards will vest, without regard to whether such Awards are otherwise vested in accordance with their terms, and (subject to Sections 5.2(c), 13.4 and 17(a)) to waive any relevant scheduled expiry dates. 

 

	9.	RECOUPMENT 

 The Participant agrees that his or her Awards may be subject to recoupment
or clawback by the Corporation and that he or she is bound by the Recoupment Policy. 
  

	10.	NON-ASSIGNABILITY AND NON-TRANSFERABILITY OF AWARDS 


An Award granted pursuant to the Plan is personal to the Participant and may not be assigned, transferred, charged, pledged or otherwise
alienated, other than to a Participant’s Permitted Assigns or Personal Representatives. 
  

	11.	ADJUSTMENTS 

  

	11.1	Adjustments 

 The number and kind of common shares to which an Award pertains and the
Exercise Price will be adjusted in the event of a reorganization, recapitalization, stock split or redivision, reduction, combination or consolidation, stock dividend, combination of shares, merger, rights offering or any other change in the
corporate structure or shares of the Corporation, in such manner, if any, and at such time, as the HR&CC may determine to be equitable in the circumstances. Failure of the HR&CC to provide for an adjustment will be conclusive evidence that
the HR&CC has determined that it is equitable to make no adjustment in the circumstances. If an adjustment results in a fractional share, the fraction will be disregarded. 

  
 9 









	11.2	No Rights to Additional Securities 

 If at any time the Corporation grants to its
shareholders the right to subscribe for and purchase pro rata additional securities of any other corporation or entity, there will be no adjustments made to the common shares or other securities subject to an Award in consequence thereof and the
Awards will remain unaffected. 
  

	11.3	Adjustments Cumulative 

 The adjustments provided for in this Section 11 will be
cumulative. 
  

	11.4	Deemed Amendments 

 On the happening of each and every of the foregoing events, the
applicable provisions of the Plan will be deemed to be amended accordingly and the HR&CC will take all necessary action so as to make all necessary adjustments in the number and kind of securities subject to any outstanding Award (and the Plan)
and the Exercise Price. 
  

	12.	PRIORITY OF AGREEMENTS 

  

	12.1	Priority of Agreements 

 In the event of any inconsistency or conflict between the
provisions of a Participant’s Award Agreement and the Plan, the provisions of the Plan will prevail with respect to such Participant. 
  

	12.2	No Duplication 

 There shall be no duplication of payments or other entitlements under
the Plan, a Participant’s Award Agreement and a Participant’s Executive Employment Agreement. 
  

	13.	AMENDMENT, SUSPENSION OR TERMINATION OF PLAN AND AWARDS 

  

	13.1	Discretion to Amend the Plan and Awards 

 The HR&CC may amend, suspend or
discontinue the Plan or Awards at any time, provided, however, that no such amendment, suspension or discontinuance may materially and adversely affect any outstanding Award granted to a Participant without the consent of the Participant, except to
the extent required by applicable law. Without limiting the foregoing, the HR&CC is specifically authorized to amend the terms of the Plan, and the terms of any Awards granted under the Plan, without obtaining shareholder approval, to: 

 

	 	(a)	amend the vesting provisions in circumstances involving the death, disability, retirement or termination of Participants; 

  

	 	(b)	amend the provisions relating to a Change in Control; 

  

	 	(c)	amend the termination provisions, except as otherwise provided in Section 13.2; 

  

	 	(d)	amend the eligibility requirements of Eligible Participants which would have the potential of broadening or increasing Insider participation, except as otherwise provided in Section 13.2(g); 


  
 10 









	 	(e)	add any form of financial assistance; 

  

	 	(f)	amend a financial assistance provision which is more favourable to Eligible Participants; and 

  

	 	(g)	make other amendments of a housekeeping nature. 

 Any amendments under this Section will be
subject to all necessary regulatory approvals. 
  

	13.2	Amendments Requiring Shareholder Approval 

 Notwithstanding Section 13.1, no
amendments to the Plan or Awards to: 
  

	 	(a)	reduce the Exercise Price, or cancel and reissue any Options or other entitlements so as to in effect reduce the Exercise Price; 

  

	 	(b)	change the manner of determining the Exercise Price so that the Exercise Price is less than the Fair Market Value on the Grant Date; 


 

	 	(c)	extend the term of an Option beyond its original expiry date, other than in accordance with Section 14.3; 

  

	 	(d)	increase the fixed maximum number of common shares reserved for issuance under the Plan (including a change from a fixed maximum number of common shares to a fixed maximum percentage of common shares);


  

	 	(e)	revise the insider participation limits set out in Section 4.3; 

  

	 	(f)	revise Section 10 to permit Awards granted under the Plan to be transferable or assignable other than for estate settlement purposes; 


 

	 	(g)	amend the definition of “Eligible Participant” that may permit the introduction or reintroduction of non-executive directors on a discretionary basis; or


  

	 	(h)	revise the amending provisions set forth in Section 13.1 or 13.2, 

 will be made without
obtaining approval of the shareholders of the Corporation in accordance with the requirements of any stock exchange upon which the common shares are then listed. 
  

	13.3	Amendment, Suspension or Discontinuance 

 No amendment, suspension or discontinuance of
the Plan or of any Award may contravene the requirements of any stock exchange upon which the common shares are then listed nor any securities commission or other regulatory body to which the Plan or the Corporation is now or may hereafter be
subject to. Termination of the Plan will not affect the ability of the HR&CC to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

 

	13.4	Tax Provisions 

 Notwithstanding the foregoing, no amendment to the Plan will cause the
Plan or any Awards granted to a Canadian Taxpayer hereunder to be made without the consent of such Canadian Taxpayer if the result of such amendment would be to cause any Award to be or become a “salary deferral arrangement” under the
Income Tax Act (Canada). 

  
 11 









	14.	TERM OF AWARD, EXPIRY, FORFEITURE AND TERMINATION OF AWARDS / BLACKOUT PERIODS 

  

	14.1	Term of Award 

 Subject to Section 14.3, in no circumstances will the term of an
Award exceed 10 years from the Grant Date. 
  

	14.2	Expiry, Forfeiture and Termination of Awards 

 If for any reason an Award expires
without having been exercised or is forfeited or terminated, and subject to any extension thereof in accordance with the Plan, such Award will forthwith expire and be forfeited and will terminate and be of no further force or effect. 

 

	14.3	Blackout Periods 

 Notwithstanding any other provision of the Plan, except as provided
in Section 4.4 of the Addendum, if the expiry date or vesting date of an Award is (i) during a Blackout Period, or (ii) within 10 Business Days following the end of a Blackout Period, the expiry date or vesting date (as applicable)
will be automatically extended for a period of 10 Business Days following the end of the Blackout Period. 
  

	15.	MISCELLANEOUS 

  

	15.1	No Rights as a Shareholder

	 	(f)	A period of absence from active employment by a Participant of 5 or more consecutive Business Days that is not a Leave of Absence or that is not in accordance with the vacation policy of the Corporation or Affiliate (as
applicable) will not constitute continuous employment by the Participant with the Corporation or Affiliate.

 ADDENDUM A – SPECIAL PROVISIONS APPLICABLE TO US TAXPAYERS 

 

	1.	 STATEMENT OF PURPOSE 



This Addendum sets forth special provisions that apply any Participant who is a US Taxpayer and forms part of the Plan. All capitalized terms,
to the extent not otherwise defined herein, will have the meanings set forth in the Plan. 
  

	2.	 DEFINITIONS 


  


	2.1	 For the purposes of this Addendum: 



Affiliate: in order to qualify as an “Affiliate” under the Plan, the entity must also be treated as a single employer
with the Corporation under Sections 414(b) and (c) of the US Code. 
 Beneficiary means any Person designated by a US Taxpayer
by written instrument filed with the HR&CC to receive any amount payable under the Plan in the event of the US Taxpayer’s death or, failing any such effective designation, the US Taxpayer’s surviving spouse; if the US Taxpayer is not
married, then the US Taxpayer’s estate. 
 ERISA means Title I of the Employee Retirement Income Security Act of
1974 and any applicable binding regulatory guidance thereunder. 
 Fair Market Value with respect to a Non-Qualified Stock Option will be the fair market value determined by the reasonable application of a reasonable valuation method, within the meaning of US Code Section 409A. 

US Code means the United States Internal Revenue US Code of 1986 and any applicable United States Treasury Regulations and other
binding regulatory guidance thereunder. 
 US Code Section 409A means Section 409A of the US Code and the
regulations and other guidance promulgated thereunder. 
 US Code Section 409A Award means an Award that is
“nonqualified deferred compensation” within the meaning of US Code Section 409A. 
 US Taxpayer means a Participant
who is a citizen or resident of the United States for purposes of the US Code, or whose Awards under the Plan are subject, or would be subject, absent an exemption, to US Code Section 409A. 

 

	3.	 ERISA 


  

	3.1	 General 



The Plan is intended to be exempt from the provisions of ERISA as a plan “maintained outside of the U.S. primarily for the benefit of
persons substantially all of whom are non-resident aliens” (within the meaning Section 4(b)(4)) of ERISA). If the Plan ever fails to meet that standard, then any US Taxpayer subject to the income tax
provisions of the US Code must be part of a “select group of management or highly compensated employees.” 

  
 A-1 









	4.	US CODE SECTION 409A 

  

	4.1	General 

  

	 	(a)	It is intended that the payments and benefits provided under the Plan will either be exempt from the application of, or comply with, the requirements of US Code Section 409A. The Plan will be construed,
administered, and governed in a manner that effects such intent, and the Corporation will not take any action that would be inconsistent with such intent and will make payments in such time and manner as the Corporation determines would minimize or
reduce the risk of adverse taxation under US Code Section 409A. 

  

	 	(b)	In the event that the Corporation reasonably determines, after consultation with tax counsel, that any compensation or benefits payable under the Plan may be subject to taxation under US Code Section 409A, the
Corporation, after consultation with the US Taxpayer, will have the authority to adopt, prospectively or retroactively, such amendments to the Plan or to take any other actions it determines necessary or appropriate to (i) exempt the
compensation and benefits payable under the Plan from US Code Section 409A, or (ii) comply with the requirements of US Code Section 409A. In no event, however, will this Section or any other provisions of the Plan be construed to
require the Corporation to provide any gross-up for the tax consequences of any provisions of, or payments under, the Plan and the Corporation will have no responsibility for tax consequences to the US
Taxpayer (or his or her Beneficiary) resulting from the terms or operation of the Plan and any and all tax liability and penalties resulting from non-compliance with US Code Section 409A will remain the
sole responsibility of the US Taxpayer. 

  

	4.2	Separation from Service 

 All references to “termination of employment” or
forms and derivations thereof in connection with the US Taxpayer’s right to receive any payment which is subject to US Code Section 409A will refer solely to events which constitute a “separation from service” (as defined in
Treasury Regulation §1.409A-1(h). 
 Notwithstanding anything to the contrary in the Plan, if
any US Code Section 409A Award constitutes a “deferral of compensation” subject to US Code Section 409A, no payment of any amounts or benefits subject to US Code Section 409A upon or following a termination of employment
under the Plan shall be made with respect to a US Taxpayer prior to the US Taxpayer’s “separation from service”. 
  

	4.3	Separate Payments 

 Each installment of the payments and benefits provided for in the
Plan will be deemed a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). 
  

	4.4	Delayed Payments 

 Notwithstanding anything in the Plan to the contrary, if the US
Taxpayer is a “specified employee” (within the meaning of Section 409A(a)(2)(B)(i) of the US Code) on the Termination Date, in the case of any payment made or benefit provided pursuant to the Plan that is considered to be a
“deferral of compensation” subject to US Code Section 409A and which is payable upon the US Taxpayer’s “separation from service” (within the meaning of US Code
Section 409A-1(h)) and which otherwise is payable within 6 months of such “separation from service”, the payment date for such payment or benefit will be the date that is the first day of the
seventh month after the date of the US Taxpayer’s “separation from service” (determined in accordance with US Code Section 409A). However, notwithstanding anything to the contrary contained in this Section or anywhere else in the
Plan, no delay will be required under this Section to the extent that such payments do not constitute a “deferral of compensation” under Treasury Regulation Section 1.409A-1(b)(4) or 1.409A-1(b)(9)(iii). 

  
 A-2 









	4.5	Deferred Compensation 

 Notwithstanding any provision to the contrary, if any
reimbursements or in-kind benefits provided by the Corporation pursuant to the Plan would constitute deferred compensation that is subject to and not exempt from US Code Section 409A, such reimbursements
or in-kind benefits will be subject to the following rules: (i) the amounts eligible for reimbursement, or the in-kind benefits provided, during any calendar year
may not affect the expenses eligible for reimbursement, or the in-kind benefits provided, in any other calendar year; (ii) any reimbursement of an eligible expense will be made on or before the last day
of the calendar year following the calendar year in which the expense was incurred; and (iii) the US Taxpayer’s right to an in-kind benefit or reimbursement is not subject to liquidation or exchange
for cash or another benefit. 
  

	4.6	“Excess Parachute Payment” 

 Notwithstanding any provision of the Plan to the
contrary, if any payment or benefit to be paid or provided hereunder or under any other plan or agreement would be an “Excess Parachute Payment,” within the meaning of Section 280G of the US Code, but for the application of this
sentence, then the payments and benefits to be paid or provided hereunder will be reduced to the minimum extent necessary (but in no event to less than zero) so that no portion of any such payment or benefit, as so reduced, constitutes an Excess
Parachute Payment; provided, however, that the foregoing reduction will be made only if and to the extent that such reduction would result in an increase in the aggregate payments and benefits to be provided, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Section 4999 of the US Code, or any tax imposed by any comparable provision of state law, and any applicable federal, state and local
income taxes). The determination of whether any reduction in such payments or benefits to be provided hereunder is required pursuant to the preceding sentence will be made at the expense of the Corporation, if requested by US Taxpayer or the
Corporation, by the Corporation’s independent accountants or a nationally recognized law firm chosen by the Corporation. The fact that the US Taxpayer’s right to payments or benefits may be reduced by reason of the limitations contained in
this Section will not of itself limit or otherwise affect any other rights of the US Taxpayer under the Plan. 
  

	5.	STOCK OPTIONS 

  

	5.1	Non-Qualified Stock Options 

 Awards granted
under the Plan will not be designated or qualify as “incentive stock options” as defined in Section 422 of the US Code. 
  

	5.2	Term of Option 

 Notwithstanding any provision of the Plan to the contrary, in no
circumstances will the term of an Option exceed 10 years from the Grant Date or be exercisable after the expiration of 10 years from the Grant Date. 
  

	5.3	Exercise Price 

 The Exercise Price of an Option will not be less than 100% of the Fair
Market Value of the common shares as determined as of the Grant Date. 

  
 A-3 









	6.	TAXES 

  

	6.1	Payment of Taxes 

 Each US Taxpayer is solely responsible and liable for the
satisfaction of all taxes and penalties that may be imposed on or for the account of such US Taxpayer in connection with the Plan or any other plan maintained by the Corporation or Affiliate (as applicable) (including any taxes and penalties under
US Code Section 409A), and neither the Corporation nor Affiliate will have any obligation to indemnify or otherwise hold such US Taxpayer (or any US Taxpayer ) harmless from any or all of such taxes or penalties. 

 

	6.2	Tax Withholding 

 A US Taxpayer will be required to pay to the Corporation, and the
Corporation will have the right and is hereby authorized to withhold, from any cash or other compensation payable under the Plan, or from any other compensation or amounts owing to the US Taxpayer, the amount of any required withholding taxes in
respect of amounts paid under the Plan and to take such other action as may be necessary in the opinion of the Corporation to satisfy all obligations for the payment of such withholding and taxes. 

 

	7.	MISCELLANEOUS 

  

	7.1	Non-Assignability 

 Section 10 of the Plan
will only be available to US Taxpayers with respect to Awards to the extent permissible under US law. 
  

	7.2	Amendments 

 Any amendments will be made in a manner consistent with the requirements of
US Code Section 409A. 
  

	7.3	Adjustments 

 Any adjustments will be made in a manner consistent with the requirements
of US Code Section 409A. 
  

	7.4	Priority 

 Except as specifically provided in this Addendum, the provisions of the Plan
and the US Taxpayer’s Award Agreement will govern. In the event of any inconsistency or conflict between the provisions of (i) the Plan and/or a US Taxpayer’s Award Agreement, and (ii) this Addendum, the terms of this Addendum
will prevail.
